Android 4.4 上实现透明导航栏和状态栏 Translucent system bar

Translucent system UI styling
To get the most impact out of your content, you can now use new window styles and themes to request translucent system UI, including both the status bar and navigation bar. To ensure the legibility of navigation bar buttons or status bar information, subtle gradients is shown behind the system bars. A typical use-case would be an app that needs to show through to a wallpaper.

这个是Android Developer上的原文反正我也看得不是很懂我知道的就是实现和导航栏和状态栏的透明带一些渐变效果

1. 设置主题

<style name="Theme.Timetodo" parent="@android:style/Theme.Holo.Light">
    <!-- translucent system bars -->
    <item name="android:windowTranslucentStatus">true</item>
    <item name="android:windowTranslucentNavigation">true</item>
</style>

添加了这两个属性之后就是是这个效果了可以看到 listview已经被顶到上面去了不知道是不是bug 查了下资料目前的解决办法好像都是给layout设置padding来解决

2.设置颜色和设置padding

private void initSystemBar() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        setTranslucentStatus(true);
        SystemBarTintManager tintManager = new SystemBarTintManager(this);
        tintManager.setStatusBarTintEnabled(true);
        tintManager.setStatusBarTintResource(R.color.actionbar_bg);
        SystemBarConfig config = tintManager.getConfig();
        listViewDrawer.setPadding(0, config.getPixelInsetTop(true), 0, config.getPixelInsetBottom());
    }
}
